Fix MSVC build errors from too many tests

Compiling some test .cpp files with MSVC can fail with the following
error:

    C1128: number of sections exceeded object file format limit: compile with /bigobj

Enable the /bigobj flag to fix the build.

This commit should not change the behavior of tests aside from making
them compile.
